TECHNICAL FIELD

Embodiments of the present invention relate to computer technologies, and in particular, to a fingerprint recognition method and a mobile terminal.

BACKGROUND

With scientific and technological progress, a fingerprint recognition technology is gradually integrated into a computer technology. Fingerprint applications on an existing mobile terminal generally include security-related applications and non-security-related applications. Examples of the security-related applications are fingerprint-based payment applications. The non-security-related applications are applications such as piano playing or font adjustment. There may be two execution environments on the existing mobile terminal, such as a rich execution environment (REE) and a trusted execution environment (TEE). Each execution environment includes an application, an operating system (OS), a driver module, and the like. (1) An OS included in the REE is a rich operating system (Rich OS) (optionally, the operating system is configured to generate and maintain a standard runtime environment, and is an operating system that has a strong processing capability and a multimedia function), such as an Android operating system. An application included in the REE is a client application (CA). (2) An OS included in the TEE is a trusted operating system (Trusted OS) (optionally, the operating system is configured to generate and maintain a secure runtime environment, and is a trusted operating system that has a secure processing capability and that provides a secure peripheral operation). An application included in the TEE is a trusted application (TA). The Trusted OS and the Rich OS are operating systems coexisting on the mobile terminal. Software and hardware resources of the Trusted OS are isolated from those of the Rich OS. In addition, the Trusted OS may provide a security service for the Rich OS. The CA may establish a session connection with the TA in the TEE by using a system switchover interface (such as a TEE client interface or a TEE function interface) (the system switchover interface is configured to provide a channel for establishing the session connection with the TA by the CA). The TA running in the Trusted OS that is isolated from the Rich OS may provide a related security function for the CA in the REE or another TA in the TEE, so as to prevent an attack of software/malicious software.

In the prior art, a fingerprint verification function is integrated into the TEE to ensure security of fingerprint information. Therefore, when fingerprint verification needs to be performed for any CA running in the Rich OS on the mobile terminal, switchover to the TEE needs to be first performed by using the system switchover interface (such as the TEE client interface), and a session connection needs to be established with a TA in the TEE. Further, the TA invokes a TEE fingerprint interface (such as a TEE FingerPrint API) for fingerprint verification.

It can be learned that, at present, fingerprint verification can be performed only in a secure runtime environment in the prior art, and a verification manner is monotonous.

DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

In this application, a mobile terminal includes but is not limited to a mobile phone, a mobile computer, a tablet computer, a personal digital assistant (PDA), a media player, a smartphone, a smart television, a smart watch, smart glasses, a smart band, and the like.

Optionally, a first operating system mentioned in this application is configured to generate and maintain a standard runtime environment (optionally, the first operating system may be a Rich OS), such as an Android operating system, the IOS, or another operating system. This application sets no limitation thereon. A second operating system mentioned in this application is configured to generate and maintain a secure runtime environment (optionally, the second operating system may be a Trusted OS). The first operating system and the second operating system independently run on the mobile terminal. The secure runtime environment is generally an operating system that has a low storage requirement, for example, a known MobiGore operating system in the prior art. The Mobicore operating system is used in combination with a so-called secure runtime environment that is in a form of an ARM security zone (ARM TrustZone).

Optionally, a first operating system mentioned in this application is configured to generate and maintain a standard runtime environment, such as an Android operating system. This application sets no limitation thereon. A second operating system mentioned in this application is also configured to generate and maintain a standard runtime environment, such as a Windows operating system. This application sets no limitation thereon. The first operating system and the second operating system independently run on the mobile terminal.

Optionally, a first operating system mentioned in this application is configured to generate and maintain a secure runtime environment, such as a BLACKBERRY operating system. This application sets no limitation thereon. A second operating system mentioned in this application is also configured to generate and maintain a secure runtime environment, such as a Trusted OS. This application sets no limitation thereon. The first operating system and the second operating system independently run on the mobile terminal.

Optionally, first-type verification mentioned in this application may be non-security verification, and correspondingly, second-type verification is security verification. Alternatively, first-type verification may be high-speed verification, and correspondingly, second-type verification may be low-speed verification. Alternatively, first-type verification may be low-threshold verification, and correspondingly, second-type verification may be high-threshold verification. Optionally, the first-type verification and the second-type verification that are mentioned in this application may be another type of verification. The present disclosure sets no limitation thereon.

The security verification mentioned in this application indicates that the mobile terminal needs to perform fingerprint verification in the secure runtime environment. The fingerprint verification may relate to a security problem of a user and/or the mobile terminal. For example, a fingerprint is used to unlock a screen, or a fingerprint is used to perform secure payment. The non-security verification indicates that the mobile terminal may perform fingerprint verification in the standard runtime environment. The fingerprint verification does not relate to a security problem of a user and/or the mobile terminal. For example, a fingerprint is used for piano playing, soft keyboard guidance, or font adjustment.

The low-speed verification mentioned in this application indicates that the mobile terminal needs to perform fingerprint verification in the secure runtime environment. The fingerprint verification may relate to a security problem of a user and/or the mobile terminal. For example, a fingerprint is used to unlock a screen, or a fingerprint is used to perform secure payment. The fingerprint verification generally has no requirement for a verification speed of the fingerprint verification. The high-speed verification indicates that the mobile terminal may perform fingerprint verification in the standard runtime environment. The fingerprint verification does not relate to a security problem of a user and/or the mobile terminal, but has a relatively high requirement for a verification speed, and requires fast fingerprint recognition. For example, a fingerprint is used for piano playing, soft keyboard guidance, or font adjustment.

The high-threshold verification mentioned in this application indicates that the mobile terminal needs to perform fingerprint verification in the secure runtime environment. The fingerprint verification may relate to a security problem of a user and/or the mobile terminal. For example, a fingerprint is used to unlock a screen, or a fingerprint is used to perform secure payment. The fingerprint verification generally has a relatively high requirement for a verification threshold of the fingerprint verification. The low-threshold verification indicates that the mobile terminal may perform fingerprint verification in the standard runtime environment. The fingerprint verification does not relate to a security problem of a user and/or the mobile terminal, and has a relatively low requirement for a verification threshold. For example, a fingerprint is used for piano playing, soft keyboard guidance, or font adjustment.

Optionally, when the verification information includes a verification security level, a verification type of to-be-verified fingerprint information is determined according to the verification information in the following manner: if the verification security level is higher than or equal to a first preset security level (a security criterion used to determine the verification security level), determining to perform security verification (that is, second-type verification) on the to-be-verified fingerprint information; or if the verification security level is lower than the first preset security level, determining to perform non-security verification (that is, first-type verification) on the to-be-verified fingerprint information.

Optionally, when the verification information includes a verification speed, a verification type of to-be-verified fingerprint information is determined according to the verification information in the following manner: if the verification speed is greater than or equal to a first preset verification speed (a criterion used to determine a high or low verification speed), determining to perform high-speed verification (that is, first-type verification) on the to-be-verified fingerprint information; or if the verification speed is less than the first preset verification speed, determining to perform low-speed verification (that is, second-type verification) on the to-be-verified fingerprint information.

Optionally, when the verification information includes a verification threshold, a verification type of to-be-verified fingerprint information is determined according to the verification information in the following manner: if the verification threshold is greater than or equal to a first preset verification threshold, determining to perform high-threshold verification (that is, second-type verification) on the to-be-verified fingerprint information; or if the verification threshold is less than the first preset verification threshold, determining to perform low-threshold verification (that is, first-type verification) on the to-be-verified fingerprint information.

Optionally, when verification information includes at least two types of the following verification information: a verification security level, a verification speed, or a verification threshold, a verification type of to-be-verified fingerprint information is determined according to the verification information in the following manner: obtaining, by the mobile terminal in the first operating system, priorities of the at least two types of verification information; and further, determining, according to verification information that has a highest priority in the at least two types of verification information, the verification type of verifying the to-be-verified fingerprint information. Optionally, it is preset that a priority of the verification security level is higher than a priority of the verification speed and the priority of the verification speed is higher than a priority of the verification threshold. For example, when the verification information includes the verification security level and the verification speed, the verification type of the to-be-verified fingerprint information is determined according to the verification security level as follows: if the verification security level is higher than or equal to a first preset security level, determining to perform security verification on the to-be-verified fingerprint information; or if the verification security level is lower than the first preset security level, determining to perform non-security verification on the to-be-verified fingerprint information.

Optionally, when verification information includes a verification security level and a verification speed, a verification type of to-be-verified fingerprint information is determined according to the verification information in the following manner: if the verification security level is higher than or equal to the first preset security level and the verification speed is less than the first preset verification speed, determining, by the mobile terminal in the first operating system, to perform second-type verification on the to-be-verified fingerprint information; or if the verification security level is lower than the first preset security level and the verification speed is greater than or equal to the first preset verification speed, determining, by the mobile terminal in the first operating system, to perform first-type verification on the to-be-verified fingerprint information.

Optionally, when verification information includes a verification security level, a verification speed, and a verification threshold, a verification type of to-be-verified fingerprint information is determined according to the verification information in the following manner: if the verification security level is higher than or equal to the first preset security level, the verification threshold is greater than or equal to the first preset verification threshold, and the verification speed is less than the first preset verification speed, determining, by the mobile terminal in the first operating system, to perform second-type verification on the to-be-verified fingerprint information; or if the verification security level is lower than the first preset security level, the verification threshold is less than the first preset verification threshold, and the verification speed is greater than or equal to the first preset verification speed, determining, by the mobile terminal in the first operating system, to perform first-type verification on the to-be-verified fingerprint information.

To address monotony of a fingerprint verification manner in the prior art, a first fingerprint interface is added in the first operating system in this application. (1) If the mobile terminal determines, in the first operating system according to the verification information, to perform first-type verification (such as the non-security verification, the high-speed verification, or the low-threshold verification) on the to-be-verified fingerprint information, the mobile terminal may directly invoke the first fingerprint interface in the first operating system to verify the to-be-verified fingerprint information. (2) If the mobile terminal determines, in the first operating system according to the verification information, to perform second-type verification (such as the security verification, the low-speed verification, or the high-threshold verification) on the to-be-verified fingerprint information, the mobile terminal needs to switch from the first operating system to the second operating system, and invoke the second fingerprint interface in the second operating system to verify the to-be-verified fingerprint information. It can be learned that, the mobile terminal may flexibly select, according to the verification type, a corresponding fingerprint interface to perform fingerprint verification on the to-be-verified fingerprint information.

S103. If the mobile terminal determines, in the first operating system according to the verification information, to perform second-type verification on the to-be-verified fingerprint information, the mobile terminal switches from the first operating system to the second operating system, and invokes the second fingerprint interface in the second operating system to verify the to-be-verified fingerprint information.

In this embodiment of the present disclosure, the mobile terminal obtains the verification information and the to-be-verified fingerprint information in the first operating system.

Optionally, the verification information may include at least one type of the following verification information: a verification security level, a verification threshold, or a verification speed, or may include other verification information. This embodiment sets no limitation thereon.

FIG. 4 is a schematic structural architectural diagram of fingerprint verification according to the present disclosure. As shown in FIG. 4, an REE and a TEE coexist in a memory of a mobile terminal 40. The REE includes: a CA installed on a storage unit in the REE, a TEE function interface (such as a TEE Function API), a TEE client interface (such as a TEE Client API) (where the TEE function interface and the TEE client interface are system switchover interfaces, configured to invoke a trusted application TA in the TEE, that is, implement switchover from the REE to the TEE), a Rich OS, an REE fingerprint interface (such as an REE FingerPrint API, that is, the first fingerprint interface of the Rich OS, configured to invoke the fingerprint sensor to perform fingerprint verification), and a driver module that is in the Rich OS and that is corresponding to the REE FingerPrint API interface.

Optionally, in this embodiment of the present disclosure, when a user triggers a fingerprint verification request operation, the CA running in the Rich OS on the mobile terminal obtains verification information that is corresponding to the fingerprint verification request operation and to-be-verified fingerprint information of the user that is collected by the fingerprint sensor. Further, the CA directly determines, according to the verification information, a verification type (such as the first-type verification or the second-type verification) of the to-be-verified fingerprint information. Further, the CA flexibly selects, according to the verification type of the to-be-verified fingerprint information, a corresponding fingerprint interface to perform fingerprint verification on the to-be-verified fingerprint information.

Further, the driver module invokes the fingerprint sensor to verify the to-be-verified fingerprint information. (2) If the verification type is the second-type verification (such as security verification, low-speed verification, or high-threshold verification), the CA invokes the system switchover interface in the Rich OS to switch to the Trusted OS, and invokes the trusted driver module in the Trusted OS by using the second fingerprint interface.
